Abstract: PURPOSE: To provide construction free from leakage of light by so limiting the mutual relations of the outside diameter of the core of a waveguide, the space of the waveguide, the specific refractive index difference of the waveguide and  propagation wavelength region as to be within the specific range.  
     CONSTITUTION: When the outside diameter of the core of a waveguide is defined as 2aμm, the space of the waveguide as (t)μm, the specific refractive index difference of the waveguide as Δ, and a propagation wavelength region as ≤λμm, these are so arranged that the conditions expressed by aΔ 1/2 (t/a-2)/λ>1.7 are satisfied. If the above-mentioned parameters are within this range, the selection of the construction that suppresses corsstalk within a range where there are practically no problems becomes feasible in an image fiber. When a transmission system of a visible region (λ=0.4W0.7μm) is considered as an example, the construction free from leakage of light may be provided by satisfying the conditions of aΔ 1/2 (t/a-2)>1.2.

Title: Machining method by multiwire saw
Inventor: TAKATANI MASARU
IPC: B28D5/04
Filed: 1990-03-30
Abstract: PURPOSE:To hold a workpiece in an upright position through a whole period of machining time by a method wherein, after cut grooves are formed on the workpiece with a wire row and free abrasive grains, a comblike spacer having a plurality of teeth, which can be fitted into each cut groove, is fitted to the cut parts of the workpiece, and then the remaining machining is completed. CONSTITUTION:Cut grooves 9 are formed on a workpiece 5 with a wire row 1 and free abrasive grains. Then, by fitting a comblike spacer 10 to the cut grooves 9, each tooth 11 of the comblike spacer 10 is fitted into each cut groove 9 to further make the cutting, whereby the workpiece 5 is machined without causing any inclined cut. Accordingly, an abrasive liquid is sufficiently supplied into all the cut grooves 9, and the immoderate machining is not done. Further, since intervals among wafers 8 are held even after machining, wash oil reaches sufficiently every part among all the wafers 8, and there is no possibility of the wires 1 being brought into contact with the surfaces of the wafers when the wires 1 are withdrawn; therefore, there is no danger such as of the scondary cutting.

Title: Analysis of crystal orientation
Inventor: INOUE YASUAKI
IPC: G01N21/65
Filed: 1986-04-14
Abstract: PURPOSE:To determine the three-dimensional orientation of a crystal by fixing either of the polarization of incident light and scattered light and measuring the change in the scattering intensity only when the scattering intensity does not change even if the polarization directions of the incident light and scattered light are cooperatively changed. CONSTITUTION:The three-dimensional orientation of the crystal is determined by measuring the change of the scattering intensity while the polarization directions of the incident light and the scattered light are cooperatively changed in an ordinary case at the time of analyzing the crystal orientation by making use of the polarization characteristic of the Raman scattered light. Either of the incident light and the scattered light is fixed and only the other is changed only in the case in which the scattering intensity does not change and the three-dimensional orientation of the crystal cannot be determined even if the incident light is made incident along a certain specific crystal axis direction and the polarization directions of the incident light and the scattered light are cooperatively changed. The three-dimensional orientation of the crystal is determined by measuring the change of the scattering intensity generated by such change. The three-dimensional orientation of the crystal is, therefore, determined even if the incident light is made incident on the crystal from any direction.

Title: Formation of element isolation region
Inventor: SAGAWA SEIJI
IPC: H01L21/76
Filed: 1985-04-22
Abstract: PURPOSE:To prevent the generation of a crystal defect in the base, silicon substrate, and the generation of contamination of heavy metals and so forth by a method wherein a photo resist film is formed on the sidewall part of the recessed part of the nitride film, an isotropic etching is performed on the nitride film using the photo resist film as a mask and the nitride film is removed leaving the sidewall nitride film on the surface of the sidewall of the recessed part. CONSTITUTION:A second nitride film 5 is formed. Then, a positive-type photo resist is adhered on the whole surface, and after that, when an anisotropic etching is performed by an RIE method, wherein oxygen is used, a photo resist film 7 is left only under the overhang to be generated on the peripheral edge of the recessed part 4 of the second nitride film 5. Then, the second nitride film 5 is removed by a plasma etching method. According to such a way, a sidewall nitride film 5a on the surface of the sidewall of the recessed part 4 is not removed, and moreover, as the ratio of selection of etching can be largely taken, such a fact of being etched up to a thin oxide film 2a at the time the etching is performed on the second nitride film 5 is never caused. Then, when the photo resist film 7 is removed, the element isolation region is made in a structure, wherein there is no damage in a silicon substrate 1 and the oxide film 2a, and furthermore, the upper surface outside of the recessed part 4 and the surface of the sidewall of the recessed part 4 are covered with thick nitride films 3 and 5a.
